LAMP-BURN ER.

SPECIFICATION forming part of Letters Patent No. 624,794, dated May 9, 1899. Application filed January 24, 1898. Serial No. 667,752. (No model.)

To all whom it may concern: I

Be it known that I, WILLIAMS. HAMM, of Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Lam p-Burners, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings and to the numerals of reference marked thereon.

Myinvention has reference to lamp-burners, more particularly to fiame-spreaders therefor and to the means for removably securin g them in place thereon.

Lamp-burners such as are used more especially in railroad signal-lanterns have attached to the body and extending above the wick-tube a device called a flame-spreader,

by the use of which a larger flame and a flame-spreader, which can readily be done without detaching the burner from the oil-pot,

the parts maybe easily and quickly cleaned, after which the spreader is positively returned to place without danger of its getting crosswise of the wick.

To more clearly illustrate my invention, reference is directed to the accompanying drawings, inwhich Figure 1 is an elevation of a lamp-burner with my device attached, a portion of the body being broken away to more clearly show the interior. Fig. 2 is a top plan view'of the same. Fig. 3 is a cross-section on the line 3 3 of Fig. 1. Fig. 4 is a perspective View of the flamespreader detached, and Fig. 5 is an elevation of the old form of burner.

1 is the body of a lamp-burner of well-known form and construction, through the center of which rises the flat wick-tube 2. Above the body is a flame-spreader 3, with its open'rectangular base just within the upper open end of the body and surrounding the top of the wick-tube. The flame-spreader 3 is formed of sheet metal,having two opposite sides 4 4 inclined from the base upwardly and outwardly from what I term the edges of the wick-tube,while the opposite sides 5 5 incline upwardly and inwardly toward the line of projectiom of the wick, the construction being such that an elongated opening 6, is formed through the top of the spreader, as clearly seen in Fig. 2. Riveted to or formed integral with the sides 4401? the spreader aretwo supporting-arms 7 7, each of which extends upwardly at the same angle as the side '4 for a short distance and is then bent back on itself, continuing downwardly below the spreader to the wick-tube, where each one is bent down parallel with and folded around one of the edges of the wick-tube, forming together a sliding support for holding the spreader in place on the burner. The lower ends of the supporting-arms 7 7 are riveted to a' cup or disk 8, which fits snugly within the bottom of the burner-body and which has an elongated opening 9 formed therethrough for the passage of tl1e wick tube when the spreader is put in place. The edges of the cup or disk are turned up for the purpose of retaining the dirt, &rc., therein.

When the lamp-burner is to be trimmed, the wick is turned up'above the flame-spreader and wiped or out with the shears in the usual manner. Should any part of the carbon trimmed from the wick fall upon the flame spreader, it can be readily wiped therefrom. Should it pass through the flame-spreader, it will fall upon the disk 8. WVhen it becomes necessary to clean the burner, the flamefie spreader is readily removed from the wick= to position.

' It will be seen that the cleaning can be conveniently done and that any charred matter from the wick cannot fall into the body of the burner, but is collected so that it may be lifted from the burner, which is done when the flame spreader is Withdrawn. Heretofore, so far as my knowledge extends, a burner has not been provided with a removable dlust or dirt collecting device, and I do not limit myself to the exact details of construction herein described, as it is obvious that the construction may be variously modified.

Having described myinvention, I claim- 1. In a lamp-burner, the body having a ick-tube extending therethrough, in combination with a flame-spreader and a cup or disk joined together and removably mounted on the said wick-tube, substantially as set forth.

2. In a lamp-burner, a body havinga wicktube, in combination with a flame-spreader,

arms adapted to clamp the wick-tube and" support the flame-spreader, and a cup secured to the lower. end of the arms, substantially as set forth.

3. In a lamp-burner, the combination of a flame-spreader, arms supporting the same and having parallel portions and a cup secured to the arms, substantially as set forth.

4. In a lamp-burner, the combination of aflalne-spreader, arms supporting the same, anda cup having a central elongated perforation therein secured to the bottom of the arms, substantially as set forth.

pending therefrom and having flanged portions for removably connecting the attachment to a lamp-burner, and a cup secured to the lower ends of the arms and. having an elongated opening therethrough, substantially as specified.

In testimony whereof I herewith set my hand and seal.
